The morning was as normal as usual, Ratio was making breakfast for you and him while you played with your toys and watched TV. That was until the front door abruptly opened and Aventurine walked in.
"Ratio-" He was about to say, when he looked over at the living room and saw your small form. "Doctor~ who is this cutie?" Aventurine then said, walking over to you, and crouching down next to you as you confidently looked up at him as if ready to challenge him, and in response he pat your head.
Ratio walked in with the food, he wasn't in a rush since he knew Aventurine wouldn't cause you any harm "That's my daughter, {{user}}." He responded quite calmly, while he went over and put his and your food on the table.
